Magnetic Lock Installation in Covina

Short answer: Magnetic locks suit glass doors, double doors, aluminum storefronts and doors where cutting a strike pocket isn't practical. They are a weaker fit where the door must stay locked during an outage, because a maglock lets go when power is lost. In that case we'd look at an electric strike or an electrified lockset instead.

Magnetic Lock Installation in Covina, CA — Installing an electric strike for access control

A maglock is installed from the header down, and most of the work happens above your head: drilling the frame, setting brackets, pulling low-voltage cable through the ceiling and landing wires at a power supply. We schedule magnetic lock installation in Covina around your hours, starting as early as 6:30 a.m. every day, so a shop can be secure before it opens. We work until 11:30 p.m., weekends included. Tell us the door type, how it swings and who needs to get in. A few photos of the header and door edge help us arrive with the right bracket kit.

Magnetic Lock Installation in Covina: what to expect

A magnetic lock has two parts. The electromagnet, a steel housing with a coil inside, mounts to the frame, usually on the header above the door. The armature plate, a flat piece of steel, mounts to the door at the matching spot. When the coil is energized, the plate is pulled onto the magnet face with a rated holding force, commonly around 600 pounds on single-door models and 1,200 pounds or more on heavy-duty ones. Cut the power and the magnetism collapses, so there is nothing to retract and nothing to turn. The plate sits on a flexible bushing so it can seat flat against the magnet even if the door moves a little. Small things matter. A gap the thickness of a business card cuts holding force, paint or rust on the faces weakens the grip, and a plate that is out of alignment can leave a door that looks locked but pulls open with a firm tug. Good magnetic lock installation is mostly alignment, solid fastening and clean wiring.

How we can help in Covina

  • Double doors and paired magnets. On a double door, one weak side defeats the whole opening. We match the holding force to the heavier leaf, mount each plate where the door is stiff, and test by pulling at the weakest point. Wiring both locks on a single release makes them behave as one door.
  • Exit sensors and push buttons. A motion sensor above the door detects someone leaving and cuts power so the door opens. A push button, mounted near the door and wired to interrupt power directly, gives a second route out. We aim the sensor at the exit side and test it with people walking, carrying items and moving slowly.
  • Power supplies, battery backup and surge protection. Battery backup keeps a maglock holding through short outages and brownouts, though the batteries wear out and the door will release once they are exhausted. We size the battery to your preferences, explain the limits, and put a replacement date on the enclosure so the backup is not forgotten.
  • Readers, keypads and controllers. Standalone keypads handle one or two doors affordably; networked controllers manage many doors with schedules and logs. Either way the maglock follows the controller, and the exit devices stay on their own path. We write down codes, schedules and wiring so a new manager can take over.
  • Door position switches, bond sensors and monitoring. A door-position switch tells the system whether the door is open or closed. A bond sensor, built into many magnets, reports whether the plate is actually seated against the magnet. Together they separate a door that is closed from one that is truly secure. We wire them to your controller or alarm if you want status or alerts.

What's different about Covina

Clinics and medical offices near Heritage Plaza Park use maglocks on records rooms, medication areas, labs and staff corridors. Some units, such as memory care or behavioral health, use delayed-egress locks under separate rules, which we don't improvise. For ordinary doors we focus on quiet release, door monitoring and clear exits, and we coordinate with your fire alarm service so that testing doesn't disrupt patients.

Apartment complexes use maglocks on glass-door fitness rooms, leasing offices, package rooms and clubhouses. Residents' expectations are simple: the door opens when they badge, and it opens from inside. Management needs logs, easy credential changes and a way to find a door left ajar. We install door-position switches and clear exit buttons, and we ask early where the fire marshal wants alarm integration.

Inland heat stresses power supplies, batteries and plastic parts. A supply in an unvented ceiling can run hot and fail, and backup batteries age faster. Glass and aluminum doors expand in afternoon sun, which can shift plate alignment slightly through the day. We mount supplies where air moves, check alignment hot as well as cool, and put a battery replacement date on the label.

Situations this covers

  • Consider an office whose doors fell open during a blackout. The cause was a small plug-in adapter with no backup feeding two maglocks. We'd replace it with a fused, regulated supply, add battery backup so the doors hold through short outages, and recommend a mechanical keyed lock for off-hours security, so protection no longer hangs on one adapter.
  • Say an earlier installer put a maglock on an office door with a card reader and nothing else. There is no exit button, no sensor and no link to the fire alarm. We'd survey the door, explain what is missing, add a sensor, a push button and a release relay, and tell you honestly which parts the building official will care about.
  • Think of a boutique with frameless glass doors on patch fittings and a floor closer. The owner wants after-hours card access but doesn't want holes in the glass. We'd use a glass-door bracket to clamp the armature plate, mount the magnet on a header plate above the door, hide the cable in the soffit, and add a push button and sensor inside so the door always opens for anyone leaving.
  • Take a warehouse pedestrian door that opens outward onto a loading yard off Badillo Street. Forklifts bump it, and the frame is thin. A maglock may not be the best choice, because the magnet needs solid anchoring and a flexing frame loses holding force. We'd weigh a strike or an electrified exit device first, and use a maglock only if the frame can be stiffened.

From your call to the finished job

  1. Survey the door, header and exit path. On site we measure door thickness and swing, header depth and ceiling access for cable. We ask who uses the door, when and how, and where the fire alarm panel and power sources are. Photos before the visit help, but nothing replaces seeing the door.
  2. Design the release path and quote. We decide which magnet or magnets, which brackets and which release devices the door needs: sensor, button, fire alarm relay and credentials. The written quote shows each piece and flags anything that needs an electrician, fire alarm contractor or building official before work begins.
  3. Mount the magnet and armature plate. The magnet face and plate must meet flat. We check the gap, adjust the plate until contact is even, and clean both faces so no paint, dust or tape sits between them. Small gaps cost large amounts of holding force.
  4. Run the power, sensors and fire alarm release. Wiring decides reliability. We use wire of the right gauge for the distance, land connections on terminals instead of twisting wires together, and fuse the supply. Exit devices get their own path, so one failed component can't trap anyone.
  5. Program credentials and set the timers. Programming depends on the controller. A standalone keypad takes a few settings; a networked system takes a user list and schedules. We create the first credentials with you, show you how to add and delete them, and leave the settings recorded.
  6. Test every release and hand over. Handover includes a short checklist: monthly button test, periodic cleaning of the plate and magnet face, and battery replacement every few years. We write the lock model, voltage and holding force on a label inside the enclosure, so future service doesn't start with guesses.

Pricing factors

  • Door type and mounting hardware. Heavy glass, wide double doors and odd headers all add to hardware needs. We would rather quote a solid kit that holds than a cheap bracket that flexes, because a flexing bracket costs holding force and, sooner or later, trust.
  • Holding force and number of leaves. Each additional leaf or door adds a lock, a plate, brackets and wiring. Several doors in one visit share survey time and programming, which lowers the cost per door, but we still quote each opening separately so you can approve some doors now and others later.
  • Cable route and header access. Where power comes from affects cost as much as hardware. A supply close to the door is cheap; one across the building means heavier wire and more labor. Sometimes moving the supply saves more than any other decision. We look for the nearest ceiling space or closet during the survey.

Advice before you book

  • If you rent, ask the landlord in writing before anyone drills the frame. A maglock may need removal when you leave, so keep a copy of the wiring diagram, the model information and any hardware that was taken out. The next tenant, and your landlord, will thank you.
  • Stand at the door and ask yourself: if the lights went out and I had never been here, could I leave? If the answer needs a sign, a hidden button or a staff member's help, the design isn't finished. Say so when you call us in Covina; we start with the exit.
  • Review who holds access a few times a year. Cards and codes pile up as staff, vendors and contractors come and go, and every extra credential is a door that opens for someone. Remove what you no longer need and keep a short list of current holders.
  • Keep banners, window film and signs off the header and away from the lock. Heat and adhesive can affect the magnet face and the sensor, and a sign can hide the release button. A tidy, visible door is a safer door.

What not to do

  • Installing the lock without an exit plan. A maglock with a card reader and nothing else can trap people if the controller fails while the lock stays energized. A sensor, push button and fire alarm release aren't optional on exit doors, and an inspector will look for them.
  • Mounting the magnet to a hollow, thin or flexible header. It may feel solid when installed and then give way under a hard pull. Anchor into steel, solid blocking or a backing plate that spreads the load across the frame.
  • Using a maglock where the door must stay latched. Fire-rated doors, some stairwells and other openings need hardware that latches positively, which a maglock does not do. Ask your building department before you specify one. If you are not sure how your door is classified, look for a label on the edge of the door or frame.

Frequently asked questions

Do I need a permit for a magnetic lock?

Possibly. Locking an exit door is a life-safety change, so some buildings require a permit, plan review or inspection, while others only want the fire alarm release tested. We tell you what we expect, and your Covina building department or fire marshal confirms. If a fire alarm or electrical contractor is needed, we flag that in the quote.

What happens to a maglock when the power goes out?

It lets go. A magnetic lock holds only while powered, so a blackout, tripped breaker or failed supply releases the door unless battery backup keeps it energized. That is good for exit safety and a risk for security. We discuss backup batteries, a mechanical key lock for off-hours and, if the door must stay locked, a strike or electrified lockset instead.

How do I secure the door after hours if power can fail?

Pair the maglock with battery backup for short outages, and consider a mechanical keyed lock for longer closures, as long as the exit rules for that door allow it. For doors that must stay locked through any outage, an electric strike or electrified lockset is a better fit. We walk you through which setup suits your door.

Should I choose a maglock or an electric strike?

If the door has a sound latch and you want free exit, key override and a door that stays locked in an outage, a strike is usually better. If the door is glass, double or has no frame to cut, or the latch can't be used, a maglock fits. We compare both for your door as part of access control installation.

Are magnetic locks allowed on exit doors in California?

They can be, when installed to the exit rules the building code sets: a way for people to leave without special knowledge, such as a sensor and push button, release on fire alarm, and release when power fails. Details vary by building and occupancy, and your fire marshal or building department decides. We design to those rules and tell you what to confirm.

Will a card reader or keypad work with a magnetic lock?

Yes. A reader or keypad signals a controller, which releases the lock for a few seconds. Cards, fobs, PIN codes and mobile credentials all work, as long as the controller's relay is rated for the lock. We connect the reader, set release times and programming, and test each credential type before we leave.

How far is Covina from your base?

Covina is about 39 miles from our San Bernardino base, roughly 45 minutes in light traffic. Arrival time depends on traffic and on the job the technician is finishing, so we give you an estimate on the phone before you commit.
